Title: Talking level compensation system
Inventor: MIWATA YASUHIKO
IPC: H04Q1/54
Filed: 1988-06-16
Abstract: PURPOSE:To simply obtain prescribed talking quality by adding loss information comprising a relay stage number or a talking loss coefficient of a relay line to a selection signal selecting a terminal equipment, using a specific exchange to analyze loss information and inserting and connecting a 2-way amplifier having a prescribed gain to a channel according to the result. CONSTITUTION:Exchanges 11-17 use a loss information addition means 31 so as to add a relay stage number or a talking loss coefficient of a relay line as loss information to a selection signal and sends the result to an exchange of the next stage. The operation is repeated and the exchange having a 2-way amplifier 32 having a prescribed gain analyzes the loss information sent by an amplifier insertion means 33, inserts and connects the amplifier 32 to the channel when the loss is a prescribed value or over, selects the loss information as the subtraction of the loss so far from the gain of the 2-direction amplifier and the result is sent to the exchange of the next stage. Thus, when the relay loss is a prescribed value or over, the two-direction amplifier 32 is inserted and connected to the channel automatically. Thus, prescribed speech quality is obtained simply.
